An analysis of early and long-term gender-related outcomes after thoracic endovascular aortic repair.

Objectives: To evaluate gender-related outcomes during endovascular treatment of thoracic and thoraco-abdominal aortic diseases (TEVAR).

Methods: Multicentre, retrospective, observational cohort study. All TEVARs between January 2005 and April 2023 were identified.

Genetic dependencies associated with transcription factor activities in human cancer cell lines.

Transcription factors (TFs) are important mediators of aberrant transcriptional programs in cancer cells. In this study, we focus on TF activity (TFa) as a biomarker for cell-line-selective anti-proliferative effects, in that high TFa predicts sensitivity to loss of function of a given gene (i.e.

Endovascular aneurysm repair under local anesthesia through bilateral percutaneous femoral access is a safe strategy to improve early outcomes and reduce hospital stay.

Background: To estimate the impact of anesthetic conduct, alone and in combination with the type of femoral access, on early results after endovascular aneurysm repair (EVAR).

Methods: A retrospective multicenter analysis on patients undergoing elective standard EVAR at four academic centers was performed. Patients undergoing the procedure through either local or general anesthesia were compared.

Infrared Resonance Raman of Bilayer Graphene: Signatures of Massive Fermions and Band Structure on the 2D Peak.

Few-layer graphene possesses low-energy carriers that behave as massive Fermions, exhibiting intriguing properties in both transport and light scattering experiments. Lowering the excitation energy of resonance Raman spectroscopy down to 1.17 eV, we target these massive quasiparticles in the split bands close to the point.

Determining the impact of an artificial intelligence tool on the management of pulmonary nodules detected incidentally on CT (DOLCE) study protocol: a prospective, non-interventional multicentre UK study.

Introduction: In a small percentage of patients, pulmonary nodules found on CT scans are early lung cancers. Lung cancer detected at an early stage has a much better prognosis. The British Thoracic Society guideline on managing pulmonary nodules recommends using multivariable malignancy risk prediction models to assist in management.

Excitonic Effects in Energy-Loss Spectra of Freestanding Graphene.

In this work, we perform electron energy-loss spectroscopy (EELS) of freestanding graphene with high energy and momentum resolution to disentangle the quasielastic scattering from the excitation gap of Dirac electrons close to the optical limit. We show the importance of many-body effects on electronic excitations at finite transferred momentum by comparing measured EELS to ab initio calculations at increasing levels of theory. Quasi-particle corrections and excitonic effects are addressed within the GW approximation and the Bethe-Salpeter equation, respectively.

Mechanisms of Resistance to Immunotherapy in Hepatocellular Carcinoma.

Systemic treatment for advanced hepatocellular carcinoma (HCC) has been revolutionized over the last few years following the approval of immune checkpoint inhibitors (ICI). Despite the promising survival extension seen with ICI combination regimens, responses are not universally seen and the optimal partner for programmed cell death 1 pathway inhibitors remains to be identified. Even fewer encouraging results have been demonstrated with ICI used for monotherapy.

Twenty-Five Year Multicentre Experience of Explantation of Infected Abdominal Aortic Endografts.

We report a multicenter experience of open conversions (OC) for aortic endograft infections (AEI). We retrospectively analyzed all patients who underwent OC for AEI after endovascular aneurysm repair (EVAR), from 1997 to 2021 in 12 Italian centers. The endpoints were as follows: mortality (30-days, in-hospital), major postoperative complications.

Probing Enhanced Electron-Phonon Coupling in Graphene by Infrared Resonance Raman Spectroscopy.

We report on resonance Raman spectroscopy measurements with excitation photon energy down to 1.16 eV on graphene, to study how low-energy carriers interact with lattice vibrations. Thanks to the excitation energy close to the Dirac point at K, we unveil a giant increase of the intensity ratio between the double-resonant 2D and 2D^{'} peaks with respect to that measured in graphite.

Integrated phenotyping of the anti-cancer immune response in HIV-associated hepatocellular carcinoma.

Background & Aims: HIV-seropositivity shortens survival in patients with hepatocellular carcinoma (HCC). Although risk factors for HCC including HCV infection can influence T cell phenotype, it is unknown whether HIV can influence functional characteristics of the T cell infiltrate.

Methods: From the Liver Cancer in HIV biorepository, we derived 129 samples of transplanted (76%) or resected (20%) HCC in eight European and North American centres.

Distribution and quantification of antibiotic resistance genes in a large subalpine lake (Lugano Lake) and tributary rivers.

Objectives: Antibiotic resistance genes (ARGs) are causing increasing problems, especially in clinical settings. Nowadays, they are considered important environmental contaminants, but little is known about their fate in the environment or how they affect natural microbial populations. In the environment, especially in water affected by anthropic activities such as discharge of hospital, urban, and industrial wastewater treatment plant (WWTP) and agricultural runoff, antibiotic determinants may become part of the environmental gene pool, spread horizontally, and be ingested by humans and animals via contaminated food and drinking water.

Clinicians' views regarding caesarean section rates in Switzerland: A cross-sectional web-based survey.

Objective: The caesarean section (CS) rate in Switzerland is currently 32 %, well above the WHO recommended rate of 15 %. The study aims were three-fold: to explore the perception of this high rate among Swiss obstetrics-gynecology (Ob-Gyn) professionals; to assess the factors associated with a perception of a too high national CS rate; and to describe professionals' opinions on measures to reduce this rate.

Study Design: A cross-sectional study was conducted between 1 May and 30 June 2021 using an online questionnaire sent to Ob/Gyn physicians and midwives at a university hospital and members of the Swiss Conference of Heads of Ob/Gyn Divisions.

Thermal conductivity of glasses: first-principles theory and applications.

Predicting the thermal conductivity of glasses from first principles has hitherto been a very complex problem. The established Allen-Feldman and Green-Kubo approaches employ approximations with limited validity-the former neglects anharmonicity, the latter misses the quantum Bose-Einstein statistics of vibrations-and require atomistic models that are very challenging for first-principles methods. Here, we present a protocol to determine from first principles the thermal conductivity () of glasses above the plateau (i.

Electron-Phonon Interaction and Longitudinal-Transverse Phonon Splitting in Doped Semiconductors.

We study the effect of doping on the electron-phonon interaction and on the phonon frequencies in doped semiconductors, taking into account the screening in the presence of free carriers at finite temperature. We study the impact of screening on the Fröhlich-like vertex and on the long-range components of the dynamical matrix, going beyond the state-of-the-art description for undoped crystals, thanks to the development of a computational method based on maximally localized Wannier functions. We apply our approach to cubic silicon carbide, where in the presence of doping the Fröhlich coupling and the longitudinal-transverse phonon splitting are strongly reduced, thereby influencing observable properties such as the electronic lifetime.

Epigenetic potentiation of somatostatin-2 by guadecitabine in neuroendocrine neoplasias as a novel method to allow delivery of peptide receptor radiotherapy.

Background: Somatostatin receptor-2 (SSTR2) is expressed on cell surface of neuroendocrine neoplasias; its presence is exploited for the delivery of peptide receptor radionuclide therapy (PRRT). Patients with no or low expression of SSTR2 are not candidates for PRRT. SSTR2 promotor undergoes epigenetic modification, known to regulate gene expression.

Female Genital Mutilation/Cutting in the Swiss HIV Cohort Study: A Cross-Sectional Study.

FGM/C is a harmful practice that involves injury of the external female genitalia without medical purpose. It is mainly practiced in Africa, Asia, and the Middle East. However, with the migratory flows, women and girls with FGM/C and its consequences live all over the world.

Gate-Tunable Magnetism and Giant Magnetoresistance in Suspended Rhombohedral-Stacked Few-Layer Graphene.

Conventionally, magnetism arises from the strong exchange interaction among the magnetic moments of d- or f-shell electrons. It can also emerge in perfect lattices from nonmagnetic elements, such as that exemplified by the Stoner criterion. Here we report tunable magnetism in suspended rhombohedral-stacked few-layer graphene (r-FLG) devices with flat bands.

A hybrid technique for the removal of a large prolapsed pedunculated submucous leiomyoma.

Uterine leiomyomas are the most common benign pelvic tumor in females. Pedunculated submucous FIGO type 0 leiomyomas may eventually protrude through the cervical canal and prolapse into the vagina taking the name of "nascent" leiomyomas. Vaginal myomectomy is the main treatment for isolated prolapsed myoma and is successful in more than 95% of cases.

NR2F2 controls malignant squamous cell carcinoma state by promoting stemness and invasion and repressing differentiation.

The nongenetic mechanisms required to sustain malignant tumor state are poorly understood. During the transition from benign tumors to malignant carcinoma, tumor cells need to repress differentiation and acquire invasive features. Using transcriptional profiling of cancer stem cells from benign tumors and malignant skin squamous cell carcinoma (SCC), we identified the nuclear receptor NR2F2 as uniquely expressed in malignant SCC.

The microscopic origin of the anomalous isotopic properties of ice relies on the strong quantum anharmonic regime of atomic vibration.

Water ice is a unique material presenting intriguing physical properties, such as negative thermal expansion and anomalous volume isotope effect (VIE). They arise from the interplay between weak hydrogen bonds and nuclear quantum fluctuations, making theoretical calculations challenging. Here, we employ the stochastic self-consistent harmonic approximation to investigate how thermal and quantum fluctuations affect the physical properties of ice XI with ab initio accuracy.
